- Q:Why can't the voice switch control the time of the LED bulb?
- The production lights can be controlled. Where do they go to consult?
- Q:LED what kinds of screw bulbs are there?
- LED bulb lights are E14, E27, E40, B22. The most common family is E27, also known as big headed screw. There are also some lamps, E14, called small headed screw. These two are the most common energy-saving light interface. Before there are B22, that is, the kind of card, also known as bayonet. It may be common in the countryside, but now it has been phased out. There are some industrial use of more E40, more than 80W energy saving lamps will be used, that is, the interface is relatively thick.
- Q:What are the requirements of the LED series inspection specification for bulb bulbs?
- Anti torque test is carried out using only suitable for torque meter, torque test, lamp holder should be firmly bonded on the lamp or lamps used to purchase spin spin out parts, E26 and E27 for 3N*m.
- Q:What's the reason for the LED bulb strobe?
- Currently on the market with single stage PFC driver circuit, there will be strobe, causing the flash because the ripple is too large. Single stage pFC circuits are not possible
- Q:Seeking the production process of LED bulb... Thanks
- First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
- Q:Is it possible to manually weld LED bulb bulbs?
- As long as the welding technology clearance is possible or OK
- Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- 5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.
- Q:What is the AC voltage of the LED bulb?
- LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 3-5 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no mercury vapor, harmful substances can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.
- Q:How to choose the bulb power?
- The basic types of bulb power are divided into two types: isolated and non isolated
- Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
